STMicroelectronics introduces the industry’s first 18nm microcontroller
for high-performance applications
- STM32V8 is the first microcontroller designed using next-generation 18nm FD-SOI technology, with advanced phase-change embedded memory (PCM)
- Selected by SpaceX for high-speed connectivity system in Starlink satellite network
- Perfectly fitted for the most demanding industrial applications such as factory automation, motor control and robotics
Geneva, November 18, 2025 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, has unveiled the STM32V8, a new generation of high-performance microcontrollers (MCUs) for demanding industrial applications. The STM32V8 is designed with ST’s most advanced 18nm process technology with best-in-class embedded phase-change memory (PCM). It is manufactured in ST’s 300mm fab in Crolles, France, and also in collaboration with Samsung Foundry. MCUs are foundational chips, with the broad portfolio of STM32 devices powering billions of devices on the planet across consumer devices, home appliances, industrial applications, medical devices and communication nodes.
“ The STM32V8 is our fastest STM32 microcontroller to date, designed for high reliability in harsh operating environments, with the ability to replace much larger and power-hungry application processors. The STM32V8 represents the future of what a high performance MCU can do for demanding embedded and edge AI applications such as industrial control, sensor fusion , image processing, voice control, and others, ” said Remi El-Ouazzane, President, Microcontrollers, Digital ICs and RF products Group at STMicroelectronics.
Thanks to its Arm® Cortex®-M85 core and the 18nm process, the STM32V8 achieves clock speeds of up to 800 MHz, making it the most powerful STM32 MCU ever shipped. High levels of faster and larger embedded memory are a key enabler of a broad range of secure and connected applications. The FD-SOI process technology with embedded PCM provides strong robustness and reliability in harsh operating environments.
One such demanding environment is the high-radiation conditions encountered in Low Earth Orbit (LEO). SpaceX has selected the STM32V8 for its Starlink constellation, using it in a mini laser system that connects the satellites traveling at extremely high speeds in LEO.
"The successful deployment of the Starlink mini laser system in space, which uses ST’s STM32V8 microcontroller , marks a significant milestone in advancing high-speed connectivity across the Starlink network.
